    O.K., moulds for the middle section are done. Will let them sit for the better part of next week at decent temperature so that everything fully sets.....

    First hull out of the new moulds. 3 mm GPR...also suitable for self defence ;-)

    Roughly put together....nevertheless, it starts to look like a boat:

    Just snapped together the support frame. 750 ml Engel tank, 12V, with Hall sensor and compact control unit. Makes the thing controllable like a servo. In the front: 4 x LiFePo

    One also can nicely see the v-shape of the stern bulkhead:

    More detail work. The handrail on the sail is installed. I used 0,5 mm brass railing posts. The rail itself is made of 0,3 mm steel wire.

    The v-shaped stern bulkhead was aligned to the stern tubes and glued into place. The bras tubes force the bulkhead into the right position:

    New project - USS Nautilus - Page 4 DSC01966_zps4nvcj82c

    The technics frame then was an easy fix. M4 thread rods and nuts. The 8 mm brass tube is the feed for the piston tank:

    Not too mach space in the back in the boat, but I want a linkage without play. That's my solution:

    Make a flat on the side of a brass set collar and drill a hole (90° to the thread). Take a brass spherical joint and shorten it:

    New project - USS Nautilus - Page 4 IMGP0373_zpse3paok5q

    Solder the shperical joint into the set collar and re-drill the center hole of the set collar:

    Done:

    Absolutely GREAT idea to get rid of any free play in the linkage.

    (parts now on my shopping list....)

    How much rotation of the shaft will this allow before the nylon housing fouls the brass collar?

    Worked allot on the sail, and some filling and grinding on the hull. Here's the current status:

    New project - USS Nautilus - Page 4 IMGP0396_zpsj7xr8bf4

    The bow got its flood holes:

    O.K., I didn't post for a while because filling and sanding is not only no fun but also doesn't look good on photos. But one can put on a big smile after finishing it....next are weld beads from Archer:

    Base colors are on. Looks quite nice. But when I put the boat outside today to get the colors dry, I recognized some minor bubbles in the dark paint. Something I'll have to take care of tomorrow (pain in the a.....):

    Started the weathering. Below the waterline the boats usually look quite shabby. I did this using David Meriman's tooth paste weathering technique. Not that bad for a first try:

    The work on the outside of the boat approaches its preliminary end. The sail is pretty much done. The masts are installed, painted and the whip-antennas are mounted as well:

    New project - USS Nautilus - Page 4 DSC02008_zpsa9l2dx8f

    New project - USS Nautilus - Page 4 DSC02010_zpsrbtdkcjh

    The bow planes are finally installed in the still controversial v-position. The bow segment of the photo-etched deck will only be installed after the boat is trimmed to allow access to the bow for additional ballast/foam for trimming:
